O'kay Roy, I'm not knocking anything you say. Ah's is only trying to get me here some learning.
Eating into zed's looking but found this below on a way earlier posting with regards to sidestand.
And, seems like omrons or MGR-C20 series relays are the way to go if upgrading relays.
Other tips or hints certainly welcome for clearing roo's!
Cheers! Jay

Subject: V11 Sport Wiring vs Relays
Dave Laing recently contacted me regarding a failed Bosch starter relay on his V11 Sport. He thought the problem was that the Normally Closed terminal of the starter relay powered the headlights, not merely the coil of the headlight relay. I was skeptical (who would be so stupid?), but after checking the wiring diagram, he is correct. Worse, that terminal (rated at 10 amps) also powers the brake lights, the tach, the horn, some of the instrument lights, and is the reference voltage for the GEN lite! Arrrrgh. The high beam and the brake lights alone are about 9 amps, and imho, too much load on a 10 amp contact. (My normal rule of thumb is to use a relay capable of twice the anticipated load).
So you ask, what controls the headlight relay? The stupid sidestand safety switch! Arrrgh. Nice going Guzzi. There is no horn relay - full current goes thru the switch. Loverly. Another buck saved.
What to do? I'd suggest:
1. Install a horn relay. It's tolerable that this relay's coil is powered thru the headlight relay, but it's horn current should come from a fuse, not from the headlight relay.
2. Remove the white/green wire from terminal 87a of the starter relay and run it instead to Fuse 5 (this is the headlight power). Disconnect the orange/blue wire from terminal 85 of the headlight relay. Run a wire from terminal 85 of the headlight relay to terminal 87a of the starter relay. Now the only load on terminal 87a (the Normally Closed terminal) of the starter relay will be the coil for the headlight relay. The difference is now the headlight will still operate if the sidestand is down.
Edit 10/12/03 Forget this option.(2.) After posting this, we discovered that it will not work....so go with option one or something else, like a higher rated relay, or a strategically wired additional relay.
Until you fix this issue, avoid using the horn and the high beam flasher.
And for what it is worth, the headlight is not deactivated by the kick stand switch.
No doubt there are other improvements that could be made to this crappy wiring layout. For example, I'd be inclined to get at least the brake lights out of the headlight circuit. My mods suggested above should greatly extend the life of the starter relay. BTW, they are made on the assumption that the bike is actually wired as shown on the diagram. Bwa, ha, ha!
Carl, may I presume that terminal 86 of the headlight relay is grounded? It's not shown as such on your diagram.
Does anyone know which other relays on this model seem failure prone?
Cheers,
Dan
